S-PLUS is a commercial implementation of the S programming language sold by TIBCO Software Inc.

It features object-oriented programming capabilities and advanced analytical algorithms.

Due to the increasing popularity of the open source S successor R, TIBCO Software released the TIBCO Enterprise Runtime for R (TERR) as an alternative R interpreter.[1]

Historical timeline[edit]

1993: Statistical Sciences acquires the exclusive license to distribute S and merges with MathSoft, becoming the firm's Data Analysis Products Division (DAPD).

1995: S-PLUS 3.3 for Windows 95/NT. Matrix library, command history, Trellis graphics

1996: S-PLUS 3.4 for UNIX. Trellis graphics, nlme (non-linear mixed effects) library, hexagonal binning, cluster methods.

1997: S-PLUS 4 for Windows. New GUI, integration with Excel, editable graphics.
